In the accompanying drawings, Figures 1 and 2 are front views of two forms of. my invention.

In Fig. l, A is an ordinary horseshoe or U magnet, having each pole provided with a half or whole doveta-iied projection, a. B is an armature, preferably of softiron, provided with notches or recesses b, to correspond to the shape of the projection c of the magnet.

In Fig. 2, A also represents a magnet and B its armature; but the armature is provided with dovetailed projections @instead of notches, which projections engage'with recesses b on the inner sides of the poles of the magnet. I
